Induction Annealing Aluminum PIpe

Induction Annealing Aluminum PIpe With High Frequency Induction Heating Machine

Objective Annealing aluminum fuel tank fill neck to 650 ยบF (343 ยบC)
Material Aluminum fill neck 2.5โ€ (63.5mm) diameter, 14โ€ (35.5cm) long
Temperature 650 ยบF (343 ยบC)
Frequency 75 kHz
Equipment โ€ขDW-HF-45kW induction heating system, equipped with aย remote workhead containing eight 1.0ฮผF capacitors for aย total of 2.0ฮผF
โ€ข An induction heating coil designed and developedย specifically for this application.
Process An eight turn helical is used to heat the tube for annealing. Toย anneal the full length of the tube, the tube is placed in the coilย and heated for 30 seconds then rotated and the bottom half isย heated for an additional 30. The tube is then bent while hot toย prevent cracking.
Results/Benefits Induction heating provides:
โ€ข High efficiency, low energy cost
โ€ข Fast, controllable and repeatable process
โ€ข Prevention of cracks
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Even distribution of heating

 

 

Induction Annealing Aluminum

Induction Annealing Aluminum With High Frequency Heating System

Objective Annealing a 1โ€ lip on aluminum cryogenic dewar that has beenย work hardened during the process of spin forming.
Material Aluminum dewar, lip has a 3.24โ€ (82.3mm) ID and is 0.05โ€ย (1.3mm) thick
Temperature 800 ยบF (427 ยบC)
Frequency 300 kHz
Equipment โ€ขDW-UHF-10KW induction heating system, equipped with aย remote workhead containing one 1.0 ฮผF capacitor.
โ€ข An induction heating coil designed and developedย specifically for this application.
Process A two turn helical coil is used to heat the lip on the cryogenicย dewar. The dewar is placed in the coil and power is applied forย 2 minutes to anneal the required 1โ€ heat zone.
Results/Benefits Induction heating provides:
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Fast, controllable, accurate heating
โ€ข High efficiency, low energy cost
โ€ข Even distribution of heating
